2022 Skywell ET5 Bluetooth and Warning Sounds Not Working

My vehicle is a 2022 Skywell ET5. The multimedia system does not transmit audio via Bluetooth, and the parking sensor sounds, turn signal sounds, and seatbelt warning alerts are not working. When I took the vehicle to the service center, they quoted me a repair cost of approximately $1,700–$1,800. This is the first time I have encountered such a brand and service experience.

In my research, I discovered that this issue happens frequently and that service centers do not provide proper assistance. This is truly a very disappointing situation.
